WHEEL AND 'BEMOUNTABLE RIM.

To all to ham it may concern: 7

Be it known that I,; JOSEPH Ennsmze, a citizen of the United States, anda res dent of Alton, in the. county of Sioux and State of Iowa, have invented certain new and useful Improvements in lVheels and Demountable Rims, of whichthe following is a specification. r I

One object of myinventionis to provide a demountable rimof such style that :a tire may be readily removed therefrom.

Another object is to provide an automobile wheel with a substantially flat portion and a rim having a portion thereof formed to easily slip over the flat portion of the Wheel. I p J Another object is to provide in a rim a spring controlled'collapsibl portion.

Another object is to provide improved means for locking the rim to the wheel.

With these and incidental objects in View, the invention consists of certain novel fea tnres of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawing which accompanies and forms 1 a part of thls specification.

In the drawing, Figure 1 is a slide elevation of my improved form of wheel and rim;

Fig. 2 is an enlarged detail of the collapsible portion of the rim; Fig. 3'is a section taken on the line 3+3, Fig. 1; Fig. 4 is a section taken on the line 44, Fig. 1; and Fig. 5 is a section taken on the line 5-5 Fig. 1. As shown in Fig. 1, the felly 1 of the wheel has a flattened portion 2; the rim b is an ordinary design up to points 4 and 5.

Hinged at 4 and 5 to the rim is a flexible rim member 6 formed by riveting to the flat spring 7 the hinge sections 8 and 9, and multiple sections 10, so spaced as to allow the spring 7 to readily flex.

Additional leaves, such as 11 and 12, are

. provided to strengthen the spring 7, and are" of'such a stiffness that they will draw the collapsible portion 6 from the arc of a circle, as shown in Fig; 1, to a flattened position, as shown in Fig. 2, when the tire13 is fully inflated. p

Suitably journaled in theflat portion 2 of the felly 1 is a shaft14to which is keyed,or otherwise suitably fastened, a cam 15, adapted to impinge against the leaf 12.straddling the plate 16 riveted to the leaf springs...

A squared head 17 on the shaft 14 provides means for turning the cam and a l Specification of Letters Patent.

Application filed October 18,1919. i Serial No. 332,081; I

Fig. 1, looks thecam in its set position, but

allows it-tov be readily turned by pressing the spring clip 18 inwardly out of engage mentwith' the squared head 17 by means of" a suitable wrench. I

When the cam 15 is retracted and the collapsible portion assumes its flattened position sufiicient clearance is provided between the rim and the felly for the rim to be readilyremoved from the wheel, and

.when the cam is extended thereby pressing spring clip 18, having a squared aperture 19, j

tions 22 therein and the rim ends at4and I 5 are provided with recesses 13 sothat when the flexible portion is collapsed the projections will lie within these recesses and clear the wheel. 7

When, however, the flexible portion is forced into the same are as the rim the proe jections 22 swing down into recesses24 in While I have described my invention and "illustrated it in one particular design, [I

do not wish it understood that I limit mythe felly so the rim may be withdrawn from self to this construction, as it isevident that r the applicationof the invention may be varied in manywa'ys within the scope of the following claims.

Claims l ar shape, but having an opening between In a'demountable rim thecombination I of a ma n portion formed of a general circufor normally holding said flexible member I in a partially flattened shape.

. 2. In a demountable rim the combination of a 'normallyarc shaped portion, a flexibleportion hinged to the ends of said arc shaped portion, and spring means ,for normally holding said flexibleportion flattened in respect to the arc of said are shapedpo'rtion.

4. In a Wheel and demountable rim the combination of a felly having one portion thereof flattened, a rim including an are shaped portion, and a flexiblel portion hinged to said are shaped portion, spring means for normally holding said flexible portion flattened in respect to said are shaped portion, and means forrforcing said flexible portion to lie in the same circle as said arc shaped portion.

5. In a Wheel and demountable rim" the combination of a felly having oneportion thereof flattened, a rim including an are shaped portion and a flexible portion hinged to said are shaped portion, spring means for normally holding said flexible' portion flattened in respect to said are shaped portion, means for forcing said flexible portion to he in the same clrcle as said are shaped portion, and means for locking said last named means. 7 v

6. In a Wheel and demountable rim the combinationj'of a'felly having one portion thereof flattened, a rim including an are shaped portion and aflexible portion hinged to said are shaped portion, spring means for normally holding said flexible portion flattened in respect to said are shaped portion,

extensions carried by said flexible portion and extending beyond the hinged joints thereof, and adaptedto lie Within recesses inthe are shaped portion ofsaid rim when said flexible portion is flattened in respect to the arc of said rim, and to'lie inrecesses in said'felly When said flexible portion lies in the arc of said rim. s i
